* if it does not exist.

* The sequence of an #arrayValue will be automatically resized and initialized

* with #nullValue. resize() can be used to enlarge or truncate an #arrayValue.

*

* The get() methods can be used to obtain default value in the case the

* required element does not exist.

* It is possible to iterate over the list of a #objectValue values using

* the getMemberNames() method.
